MOUNTING FRAME FOR DISPLACING AND FIXING IN A SHAFT

Abstract

A mounting frame for being displaced and fixed in a shaft has a main frame, a first primary fixing component for supporting the mounting frame on a first shaft wall of the shaft and a secondary fixing component for supporting the mounting frame on a second shaft wall of the shaft opposite the first shaft wall in a fixing direction during fixing of the mounting frame in the shaft. The first primary fixing component and the secondary fixing component are arranged on the main frame. The first primary fixing component and/or the main frame can assume a transport position and a working position. A change of the first primary fixing component and/or the main frame from its working position to its transport position leads to a reduction in an extension of the mounting frame in an extension direction that differs from the fixing direction.

DETAILED DESCRIPTION

[0051] FIGS. 1 and 2 will be discussed first. According to FIG. 1, a mounting system 10 for carrying out automated mounting steps has a displacement component in the form of a winch 12, which is arranged on a shaft ceiling 14 of a shaft in the form of an elevator shaft 16. The elevator shaft 16 is delimited by a total of four shaft walls, of which only a first shaft wall 18 and a second shaft wall 20 that is opposite in a fixing direction 40 are shown in FIG. 1. FIG. 2 also shows a third shaft wall 19 and a fourth shaft wall 21 opposite the third shaft wall 19. According to FIG. 2, the elevator shaft 16 has a mainly rectangular cross section and extends mainly in a vertical direction, the shaft being delimited at the top by the shaft ceiling 14. A shaft floor opposite the shaft ceiling 14 is not shown. The second shaft wall 20 has an opening in the form of a door opening 23 into which a shaft door is inserted when an elevator system is mounted in the elevator shaft 16.

[0052] The winch 12 is connected, via a suspension means in the form of a cable 22, to a mounting frame 24 of a mounting apparatus 26 for carrying out automated mounting steps in the shaft 16. The cable 22 can be wound or unwound from the winch 12 and the mounting frame 24 and thus the mounting apparatus 26 can thereby be displaced in the elevator shaft 16, i.e., pulled up and lowered down. The mounting frame 24 and thus the mounting apparatus 26 can therefore be displaced in the elevator shaft 16 in a vertically extending displacement direction 27. A mechatronic installation component in the form of an industrial robot 28 is arranged on the mounting frame 24, by means of which component mounting steps can be carried out in the elevator shaft 16 in an automated manner. The industrial robot 28 is designed, for example, like an industrial robot described in WO 2017/016780 A1, and can automatically carry out the mounting steps described in the document, for example.

[0053] The mounting frame 24 and the industrial robot 28 thus form the mounting apparatus 26 for carrying out automated mounting steps. The mounting apparatus 26, the cable 22 and the winch 12 thus form the mounting system 10 for carrying out automated mounting steps.

[0054] The mounting frame 24 has a multi-part main frame 30. The main frame 30 has a mainly cuboid central part 32 on which the industrial robot 28 is arranged so as to be suspended downward. The central part 32 can accommodate other components (not shown) of the mounting apparatus 26 or of the mounting frame 24, such as a control device and/or a compressor for providing compressed air. The central part 32 can be sealed from the outside by a housing (not shown). A side of the central part 32 oriented toward the second shaft wall 20 forms a second side 47 of the main frame 30.

[0055] The central part 32 is adjoined by three transverse beams 34a, 34b, 34c which extend horizontally and are spaced apart from one another in the displacement direction 27. The transverse beams 34a, 34b, 34c are constructed in two parts, it being possible for a first part 36a, 36b, 36c arranged toward the central part 32 to be pushed into a second part 38a, 38b, 38c arranged toward the first shaft wall 18. The two parts 36a and 38a, 36b and 38b and 36c and 38c, respectively, are arranged in each case in alignment in the fixing direction 40 and can be secured relative to one another by a bolt (not shown). In this way, the expansion or extension of the main frame 30 in the fixing direction 40, which extends horizontally and perpendicularly to the first shaft wall 18 and to the second shaft wall 20, can be changed.

[0056] The lowermost transverse beam 34c is connected, toward the first shaft wall 18, to a two-part longitudinal beam 42 extending in the displacement direction 27. A first part 49 arranged toward the transverse beam 34c can be pushed into a second part 51. The two parts 49, 51 are arranged in alignment in the displacement direction 27 and can be secured relative to one another by a bolt (not shown). In this way, the expansion or extension of the main frame 30 in the displacement direction 27 and thus in an extension direction can be changed. The main frame 30 can assume a working position and a transport position, the working position being shown in FIG. 1.

[0057] The longitudinal beam 42 forms a first side 45 of the main frame 30. At the lower end of the longitudinal beam 42, two horizontal supports 43 are arranged which project into the elevator shaft 16 and which, during operation of the mounting apparatus 26, can support one or more magazines comprising mounting material, such as screws or anchor bolts. The main frame 30 is thus composed of the central part 32, the three transverse beams 34a, 34b, 34c, the longitudinal beam 42 and the supports 43. The mentioned parts of the main frame 30 are interconnected in a suitable manner, i.e., plugged, screwed or welded, for example. For example, they are each made of suitable metal sections.

[0058] Two combinations of a supporting component 44a, 44c and a first primary fixing component 46a, 46c are arranged on the upper transverse beam 34a toward the first shaft wall 18. Only a combination of the supporting component 44a and the first primary fixing component 46a can be seen in FIG. 1. FIG. 2 shows both combinations. Toward the first shaft wall 18, two combinations of a supporting component 44b and a second primary fixing component 46b are arranged on the middle transverse beam 34b. Only a combination of the supporting component 44b and the second primary fixing component 46b can be seen in FIGS. 1 and 2.

[0059] The supporting components 44a, 44b, 44c and the primary fixing components 46a, 46b, 46c are arranged such that they each form corners of a rectangle of which the edges extend in the displacement direction 27 and in a transverse direction perpendicular to the displacement direction 27 and to the fixing direction 40, the primary fixing components 46a, 46b, 46c being arranged further outward in the displacement direction 27 than the supporting components 44a, 44b, 44c.

[0060] The primary fixing components 46a, 46b, 46c each have an arm 53a, 53b which is connected to the relevant transverse beam 34a, 34b. A primary contact element in the form of a rubber buffer 55a, 55b, 55c is arranged on the relevant arm 53a, 53b toward the first shaft wall 18.

[0061] The arms 53a of the two upper, first primary fixing components 46a, 46c are connected to the upper transverse beam 34a via a pivot axle (not shown) extending in the fixing direction 40. The arms 53a and thus the two first primary fixing components 46a, 46c are thus arranged so as to be able to pivot relative to the upper transverse beam 34a and thus relative to the main frame 30. The first primary fixing components 46a, 46c can thus assume a working position and a transport position, the working position being shown in FIG. 1. In the working position, the arms 53a extend upward away from the upper transverse beam 34a and thus from the main frame 30 in the extension direction and thus in the displacement direction 27. In order to set the transport position, shown in FIG. 3, of the first primary fixing components 46a, 46c, the arms 53a and thus the first primary fixing component 46a, 46c can be pivoted downward about the pivot axle and thus can be displaced toward the main frame 30. The transport position of the first primary fixing components 46a, 46c will be discussed in more detail in connection with FIG. 3.

[0062] The arms 53b of the two lower, second primary fixing components 46b are rigidly and therefore immovably connected to the middle transverse beam 34b and thus to the main frame 30. No part of the second primary fixing components 46b projects beyond the main frame 30 in the extension direction and thus in the displacement direction 27.

[0063] The rubber buffers 55a, 55b, 55c are arranged on the relevant transverse beam 34a, 34b and thus on the main frame 30 via the arms 53a, 53b. This connection, in the case of the second primary fixing components 46b, never permits any movement relative to the main frame 30 in the fixing direction 40, and in the case of the first primary fixing components 46a, 46c does not permit such a movement at least in their working position.

[0064] Each supporting element 44a, 44b, 44c has a roller 48a, 48b, 48c which can be rotated about an axle (not shown) and which can roll along the first shaft wall 18 in the displacement direction 27. The axles of the rollers 48a, 48b, 48c are each fastened, via a holder 50, to the arm 53a, 53b of the associated primary fixing component 46a, 46b, 46c so as to be movable in the fixing direction 40. For this purpose, the holders 50 can each have a corresponding elongate hole (not shown). Between the arms 53a, 53b and the relevant axle of the rollers 48a, 48b, 48c, energy storage means in the form of helical springs 52 are arranged such that they press the rollers 48a, 48b, 48c against the first shaft wall 18, such that the rollers 48a, 48b, 48c and thus the supporting components 44a, 44b, 44c are in contact with or supported on the first shaft wall 18 via a relevant supporting surface 54a, 54b, 54c.

[0065] A secondary fixing component 56 is arranged on the central part 32 of the main frame 30 toward the second shaft wall 20. An actuating ram 58 extending in the fixing direction 40 is mounted in the central part 32 and projects from the central part 32 toward the second shaft wall 20. The actuating ram 58 can be displaced in the fixing direction 40 by means of two actuators in the form of electric spindle drives 60, i.e., can be extended out of the central part 32 and moved into the central part 32. The actuating ram 58 is connected to a secondary contact element 64, which is elongate in the displacement direction 27, via an intermediate piece 62, which likewise extends in the fixing direction 40 and is therefore arranged in alignment with the actuating ram 58, and via a retaining plate 63. The actuating ram 58 is inserted into the intermediate piece 62 and can be secured in various positions relative to the intermediate piece 62 by a bolt (not shown). A distance between the secondary contact element 64 and the central part 32 and thus the main frame 30 in the fixing direction 40 can also be changed independently of the spindle drives 60 of the secondary fixing component 56.

[0066] The secondary contact element 64 has a multi-part design. A central piece 66 can be rigidly connected to the intermediate piece 62 via the retaining plate 63. It is also possible that the central piece 66 can be detached from the retaining plate 63 and that the secondary contact element 64 is thus designed so that it can be completely removed. The central piece 66 is adjoined in the displacement direction 27 at the top and bottom by a relevant end piece 68 that can be easily mounted and removed.

[0067] In FIGS. 1 and 2, the four supporting components 44a, 44b, 44c are in the displacement position. The rollers 48a, 48b, 48c project beyond the primary fixing components 46a, 46b, 46c toward the first shaft wall 18. In addition, the secondary contact element 64 of the secondary fixing component 56 is in the displacement position. The secondary contact element 64 is therefore not in contact with the second shaft wall 20 but is at a distance from the second shaft wall 20 in the fixing direction 40.

[0068] In this state of the mounting frame 24 and thus of the mounting apparatus 26, the frame can be displaced in the elevator shaft 16 in the displacement direction 27 by means of the winch 12 and the cable 22 and thus can be positioned at different heights. The mounting frame 24 is supported on the first shaft wall 18 via the supporting surfaces 54a, 54b, 54c of the rollers 48a, 48b, 48c. The rollers 48a, 48b, 48c roll on the first shaft wall 18.

[0069] In order to fix the mounting frame 24 and thus the mounting apparatus 26 in the elevator shaft 16, the secondary contact element 64 of the secondary fixing component 56 is displaced outward by means of the two spindle drives 60 toward the second shaft wall 20, i.e., away from the main frame 30. As long as the secondary contact element 64 has not reached the second shaft wall 20, the supporting elements 44a, 44b, 44c remain in the displacement position shown in FIGS. 1 and 2. If the secondary contact element 64 is in contact with the second shaft wall 20 and the actuating ram 58 is extended further out of the central part 32, the entire main frame 30 together with all parts arranged immovably thereon is displaced toward the first shaft wall 18. The helical springs 52 of the supporting elements 44a, 44b, 44c are then compressed until the primary fixing components 46a, 46b, 46c are in contact with the first shaft wall 18 via the rubber buffers 55a, 55b, 55c. The mounting frame 24 is thus press-fitted or clamped and thus fixed between the first shaft wall 18 and the second shaft wall 20.

[0070] In FIGS. 1 and 2, the mounting frame 24 is shown in a working state. In this working state, the frame is arranged in the shaft 16 and allows mounting in the shaft. The working state is characterized in that [0071] the first primary fixing components 46a, 46c are in their working position, i.e., the arms 53a extend upward away from the main frame 30, [0072] the main frame 30 is in its working position, and the two parts 49, 51 of the longitudinal beam 42 are pulled far enough apart for the industrial robot 28 to carry out all the necessary mounting steps, [0073] the two associated parts 36a, 38a; 36b, 38b; 36c, 38c of the transverse beams 34a, 34b, 34c are arranged relative to one another such that the central part 32 is in a desired position and it is possible to fix the mounting frame 24 in the shaft 16, [0074] the actuating ram 58 and the intermediate piece 62 of the secondary fixing component 56 are arranged relative to one another such that the central part 32 is in a desired position and it is possible to fix the mounting frame 24 in the shaft 16, and [0075] the secondary contact element 64 of the secondary fixing component 56 is completely mounted.

[0076] If the mounting frame 24 and thus the mounting apparatus 26 are to be transported, i.e., for example, to be brought to another shaft, then the mounting frame 24 is brought into a transport state which is illustrated in FIG. 3. The transport state is characterized in that [0077] the first primary fixing components 46a, 46c are in their transport position, i.e., the arms 53a are pivoted downward toward the main frame 30 such that no part of the first primary fixing components 46a, 46c projects beyond the main frame 30 in the extension direction, [0078] the main frame 30 is in its transport position, and the two parts 49, 51 of the longitudinal beam 42 are slid one into the other as far as possible, [0079] the two associated parts 36a, 38a; 36b, 38b; 36c, 38c of the transverse beams 34a, 34b, 34c are slid one into the other as far as possible, [0080] the actuating ram 58 and the intermediate piece 62 of the secondary fixing component 56 are slid one into the other as far as possible, and [0081] the secondary contact element 64 of the secondary fixing component 56 is completely removed.

[0082] In order to bring the main frame 30 from its working position into its transport position and vice versa, i.e., to slide the two parts 49, 51 of the longitudinal beam 42 one into the other or to pull them apart, an adjustment apparatus in the form of a crank 70 is arranged on the first part 49 of the longitudinal beam 42, which adjustment apparatus interacts with Bowden cables (not shown) in the two parts 49, 51 of the longitudinal beam 42. By turning this crank 70, the two parts 49, 51 can be slid one into the other and pulled apart. The crank 70 is arranged such that it can also be actuated from outside the shaft 16 if the mounting frame 24 is located in the shaft 16.

[0083] The extension of the mounting frame 24 in the extension direction and thus in the displacement direction 27 is significantly smaller in the transport state than in the working state. This reduction results from the change of the first primary fixing components 46a, 46c from their working position to their transport position and from the change of the main frame 30 from its working position to its transport position.

[0084] In addition, the extension of the mounting frame 24 in the fixing direction 40 is significantly smaller in the transport state than in the working state. This reduction results from sliding the associated parts 36a, 38a; 36b, 38b; 36c, 38c of the transverse beams 34a, 34b, 34c one inside the other, from sliding the actuating ram 58 and the intermediate piece 62 of the secondary fixing component 56 one inside the other, and from the removal of the secondary contact element 64 of the secondary fixing component 56.

[0085] Finally, it should be noted that terms such as “having,” “comprising,” etc. do not preclude other elements or steps and terms such as “a” or “an” do not preclude a plurality. Furthermore, it should be noted that features or steps that have been described with reference to one of the above embodiments can also be used in combination with other features or steps of other embodiments described above.
